Floss: Hcidoc: Allow reserved status for L2CAP connection

At least one peer device reports a reserved |status| for L2CAP
connection response. It is actually ignored since there is another
field |result| = Success, and the spec mentions |status| is only
defined for |result| = Pending.

Therefore, lets just allow any value in the PDL file so it will not be
indicated as a corrupted packet and skipped.

Bug: 325574948
Test: m -j
Test: Using report 91518762919, verify all 37 L2CAP connections are
      reported.
